SPECIFICATION forming part of Letters Patent No. 634,859, dated October10, 1899. Application filed March 14,1898. SerinlNo. 673,792. (Nomodel.)

To all whom, it may concern:

Beit known that I, CHARLES SEBASTIAN, a citizen of the United States,residing at St. Louis, in the State of Missouri, have invented certainnew and useful Improvements in Staple-Setting Machines, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming a part hereof.

My invention relates to improvements in staple-settin g machines; anditconsists in the novel combination and arrangement of parts, as will behereinafter more particularly described, and pointed out in the claims.

In the drawings, Figure 1 is a side elevation of my complete invention.Fig. 2 is a front view of the stationary jaw or head of the machine.Fig. 3 is a vertical section taken on the line a a of Fig. 2. Fig; 4: isa plan view of the spring and lug which is secured to the head. Fig. 5is a front view of the head of the machine with parts removed therefrom.Fig. 6 is a rear view of my complete invention. Fig. 7 is a verticaltransverse section taken on the line I) Z) of Fig. 8. Fig. 8 is asimilar section taken on the line 0 c of Fig. 7. Fig. 9 is a sectiontaken on the line d d of Fig. 1. Fig. 10 is a detailplan view of the camwhich operates the lever forming the lower jaw. 0 Fig. 11 is a plan viewof the receptacle for containing the staples. Fig. 12 is a section takenon the line 6 e of Fig. l, and Fig. 13 is a plan view of the cam andrear end of the lever for operating the reciprocating plunger. Theobject of my invention is to construct a machine to be employed forautomatically feeding and setting staples for securing leather or othermaterial together, thereby dispensing with hand or machine stitching 4ousually employed, and is especially adapted for uniting the variousleather parts comprising the upper portion of shoes; but the machine isequally applicable for other purposes where like results are desired tobe obtained 5 without departing from the nature of my invention.

Briefly stated, the invention consists of a main drive-shaft operatedcontinuously or intermittingly by a belt-pulley and meansoooperatingwith the latter and under the control of the operator; a camsecured to said shaft and engaging with one end of a pivoted lever theopposite end of which forms the lower movable jaw of the machine, saidcam elevating the jaw to its highest position, and

a spring for causing the same to assume its normal position; asccond camsecured to said shaft and cooperating with the inner forked end of asecond pivoted lever, the outer end of which vertically reciprocates aplunger which is brought in contact with the staple under the same,whereby the stapleis forced down and through guideway in the head of themachine and its legs brought in contact with the die carried by thelonger jaw and turned after they have been passed through the materialto be united; an inclined track leading directly from the head to andpassing into a rotating feed cylinder or receptacle upon which thestaples slide from the recep- 7o tacle to the head of the machine andunder the plunger; a spring-plate secured to the head of the machine thefree end of which is provided with an inclined lug which is normallylocated in a correspondingly-shaped groove formed in the end of thetrack; a bracket secured to the rear of the machine; a spindle securedand supported by the same; a tubular projection forming a part of therotating receptacle and adapted to turn upon said spindle and inconsequence turn said receptacle; a large grooved belt-pulley secured tosaid tubular extension; a small grooved belt-pulley secured to theprojecting end of the powershaft; an idle grooved pulley movablysupported on a spindle secured to the machine; a suitable belt passedover said pulleys, whereby when the power-shaft is rotated thereceptacle containing the staples to be fed to the track is also turnedor rotated; a sliding cover for said receptacle; a circular opening inone end of said receptacle through which the upper end of the trackpasses; a hopper secured to the inner projecting end of the spindlelocated within the receptacle, the open end of which is in a line withthe upper end of the track; plates secured to the inner curved surfaceof the receptacle for elevating the staples contained therein andpermitting them to drop into the hopper; a ring secured within thereceptacle and located at one end thereof, said ring forming a brushencircling the track, whereby only those staples that are properlyplaced upon the track are permitted to pass from the receptacle, andother details in the construction, as will be hereinafter more fullydescribed.

Referring to the drawings, 1 represents the body of the machine, whichis preferably cast in one piece, and having a forward head 2, formingone jaw, and an extension 3, terminatin g in bearin gs 4, which operateas a guide for the vertical reciprocating rod 5. To this rod isadjustably secured a collar 6, and loosely secured to the opposite sidesof the same and depending therefrom are two links 7, to the lower endsof which are loosely secured the forked ends 8 of a pivoted lever 9, ashaft 10 passing through the opposite sides of the body of the machineand lever. The rear end of the lever 9 also terminates in a fork 11,which embraces a cam 12, fixed to the rotating power-shaft 13, whereby areciprocating motion is given to the forward end of the said lever, andconsequently the rod 5, when motion isimparted to the said shaft by thebelt-Wheel 14. Located adjacent to the cam 12 is a second cam 15, whichcooperates with the rear end of a second pivoted lever 16, also mo vablysecured to the body of the machine by a shaft 17, the forward end ofwhich is adapted to move to and from the stationary jaw or head 2 andforms the lower jaw of the machine. Thus it will be seen that whenmotion is imparted to the shaft 13 the forward end of the lever 16 willbe elevated toward the fixed head 2 by the cam 15, the spring 18 forcingthe said lever in the opposite or normal position after the cam has beensufficiently turned to cause the flat surface of the same to comeopposite the rear end of the lever-or, in other words, the cam operatesthe lever in one direction and the spring operates in the oppositedirection. Any well-known clutch mechanism is employed in connectionwith the drive beltwheel 14 and operated by a rod 20 by the foot of theoperator for causing the machine to run continuously or intermittinglywhile the said wheel is being continuously rotated, whereby the latteris locked to the shaft 13 or free to turn on the same at the will of theoperator.

To the lower end of the reciprocating rod 5 is removably secured a flatplunger 21, the lower end of which is brought in contact with the uppersurface or top of the staple 22 to be set and is guided between twoplates, which are secured to the head 2 of the machine and are formed inthe manner now to be described.

The plate 23 is provided with a verticalgroove 24 of a size to-snuglybut freely admit the plunger 21, said plate also having an openingformed therein through which the delivery or lower end of the inclinedtrack 25 and guard-bar 26, running parallel with the same, passes fordelivering the staples below the plunger. Located adjacent to the plate23 is a second thin plate 27, having a slot running a portion of itslength, the width of which is a little less than the groove 24, the twoplates when united and secured to the head 2 of the machine by screws 28forming a perfect guide for the plunger and for prop erly guiding andholding the staple until the same is set through the material to besecured together.

In order to hold the staple to be set in its proper position to bestruck or operated by the plunger21, a spring-plate 29 is employed, theupper end of which is secured by the up per two screws 28, which holdthe several parts previously described together, said plate beingsusceptible of a slight adjustment by the elongated openings 30 formedtherein through which the said screws are passed, and forming a, part ofthe spring-plate is a lug 31, passing loosely through the slot in plate27, having an inclined edge 32, which is received byacorrespondingly-shaped groove formed in the end of the track, the oppositely-located shoulders 34 formed on said lug abutting against the endof the track on either side of the groove formed therein, whereby asufficient width is given the lug for holding the staple in a positiveposition and further holding the same until itis struck by the downwardmovement of the plunger. The lower or delivery end of the track isslightly curved, as shown, in order to cause the staples to assume atrue vertical position before they move under-the plunger2l. The forwardor free end of the lower jaw is provided with the usual die 35 forturning the legs of the staple inwardly after the same are forcedthrough the material to be united. The staples are fed to the trackautomatically'in the manner now tov be described,

whereby the latter is constantly filled along its entire length in orderto insure the true and perfect working of the machine at all times andunder all conditions.

Secured to the rear end of the body 1 of the machine is a bracket 36,the upper end of which rigidly supports a spindle 37, over which thetubular extension 38 of the cylindrical receptacle 39 is loosely passedand is adapted to turn thereon, and to the said tubular extension issecured a belt-wheel 40, over which a belt 41 of any suitable design ispassed for imparting a rotary motion to the receptacle.

To the projecting end of the power-shaft 13 is secured a belt-pulley 42,and loosely journaled upon a spindlesecured to the body of the machineis an idle belt-pulley 43, over which wheel and pulleys the said endlessbelt 41 passes, as best shown in 6 and for the purpose previouslydescribed.

The receptacle 39 is provided with a series of plates or wings 44,arranged around its inner circumference, which elevate the stapleslocated in the bottom of the receptacle when the latter is rotated to aheight to allow the staples to drop ,by gravity into the stationaryhopper 45, fixed to the projecting spindle 37.

The inclined track 25 leads from the open end of the said hopper and isin a position to properly receive a suitable number of staples as theypass through the hopper to always keep the track full from its receivingto its delivery end, the remaining staples or those that are notreceived or caught by the track dropping to the bottom of thereceptacle, where they are in a position to be again elevated.

At a suitable distance from the upper or receiving end of the track 25 abend of compound curvature is formed, as shown at el-(i, which operatesto prevent the staples from remaining at that end of the track.

The removable end of the receptacle is provided with an opening 47,through which the upper end of the track 25 projects, and surroundingsaid opening and located on the inside of said end of the receptacle isan annular depression 48, which operates to direct staples that have notbeen properly placed or properly dropped on the track back to the bottomof the receptacle- Secured to the removable end of the receptacle,concentric with the annular depression 48, is a rin 49, the size ofwhich is less than the circumference of said depression,whereby a spaceis left to permit the free passage of the fasteners that happen to dropinto the said depression, said ring being secured to the end of thereceptacle by lugs 50, project.- ing from the ring, and screws passingthrough the lugs and into the end of the receptacle. Should the staplesbecome linked or coupled, which often happens, and one of them is on thetrack properly, the bristles secured to the inner circumference of thering 49, which forms a circular brush, strike the staple or staplesdisplaced or carried by the one on the track and brushes it off, leavingthe one in proper position on the track, the other falling back withinthe receptacle to be elevated again with the remaining ones.

In practice the belt-wheel 40 may form an integral part of thereceptacle 39, thereby reducing the parts, and consequently the cost ofmanufacture, and further render the parts more durable.

By referring to the drawings it will be seen that the forward ends ofthe track 25 and guard 26,l0cated above the same,are made adjustable byscrews 51 and 52, passing through oppositely-located lugs 53 and 5st,forming a part of the stationary jaw 2, the ends of which are brought incontact with the rail and guard, respectively, the same being pivotallysecured near their upper ends by screws 55, passing through them andinto an extension 56, formin g a part of the body of the machine.

By the construction as above described it will be seen that the forwardends of the track 25 and guard 26 may be accurately adjusted in respectto the opening formed in the head through which the staples pass, whichis very important. Otherwise through any inaccuracyin the formation ofthe machine the staples would not be properly fed under the plun-- gerlocated within said head, and, further, it is necessary that the forwardend of the guard be properly adjusted in respect to the track in orderthat the staples may be properly held in position upon that end of thetrack before they enter the head of the machine, the guard being soadjusted as to hold the staples one behind the other.

Referring back to the stationary jaw of the machine, the delivery end ofthe track, and the springactuated lug cooperating therewith, it will beseen that when the plunger comes in contact with the staple supported onsaid lug the latter is forced outwardly as the staple is forceddownward; but the lug remains in frictional yielding contact with thestaple until it enters the guideway below the track. Thus it will beseen that the staple is held in a proper position during the entireoperation and cannot turn or become displaced, as is usually the resultin other staple-setting machines.

\Vhen the track 25 is filled with staples and the machine setin motionby the power-shaft 13, the enlarged part of the cam 15 is brought incontact with the rear end of the lever 16, forcing the forward end ofthe same toward the stationary jaw 2, and thus holding the material tobe operated on between said jaws. After the lever has been moved to itshighest position the enlarged portion of the cam 12 comes in contactwith the upper arm of the fork forming the rear end of the lever 9.,forcing the plunger in a downward direction, its lower end cooperatingwith a staple in the manner previously described. During the aboveoperation the rotating receptacle is continuously operated in order tokeep the track 25 filled with staples in order to insure the perfectworking of the machine, whereby a staple will be positively set at everycomplete rotation of the power-shaft.

A very important feature of my invention is the feeding of the materialto be operated on in direct contact with the lower surface of thestationary jaw, which operates as a guide for the operator, the materialbeing held in a position while the staple is bein set by the lowermovable jaw.

It is obvious that the machine is susceptible of various mechanicalchanges without departing from the nature of my invention. For instance,the rotating receptacle may be operated by any other well-known means.

By referring to Figs. 7 and 8 of the drawings it will be seen that acircular band 5.7 is secured to one end of the receptacle 39 of a sizein circumference to freely pass around the upper or receiving end of thehopper 4.5 and revolves about the latter, whereby only those staplesthat drop and pass through the hopper can possibly come in contact withthe track and other parts cooperating therewith. It is further to beobserved that by the employment of the bend 46 in the track 25 and thecooperation of the circular brush with said stationary head, a lowerjaw,

portion of the track the staples are started down'the track, leaving theupper end of the same free to receive additional staples.
